Meituan Technical Team's Three Papers Accepted at SIGIR 2024: Ad Auction Integration, Federated Recommendation, and POI Recommendation

Meituan’s technical team has had three papers accepted at SIGIR 2024, presenting a deep‑learning mechanism that jointly optimizes ad auction and feed allocation while preserving incentive compatibility, a retrieval‑enhanced vertical federated recommendation framework that handles non‑overlapping users and mitigates cross‑domain feature gaps, and a disentangled contrastive hypergraph learning model that separates collaborative, transfer, and geographic signals to improve next‑POI recommendation performance on real‑world data.

Meituan Mini‑Program Testability Practices and Implementation

Meituan’s Tech Salon Session 77 describes how the company built a generic JavaScript‑hooking SDK packaged as an NPM module to give mini‑programs on platforms such as WeChat, Alipay and Kuaishou observable and controllable capabilities across UI, storage, network and system layers, enabling automated cache management, request mocking, state inspection and visual diff testing, which the ticket team leveraged to achieve over 30 % test scenario coverage, 100 % page coverage and discover hundreds of defects, while outlining future plans to stabilize and expand the framework.

Applying Domain-Driven Design to Marketing System Architecture: Strategic, Tactical, and Code Practices

The article shows how Meituan’s team applied Domain‑Driven Design to restructure a B‑side marketing platform by first tackling software complexity through strategic use‑case analysis, unified language, and bounded‑context mapping, then converting the resulting concept model into a tactical object model with well‑designed aggregates, and finally implementing a hexagonal/clean/onion code architecture that places the domain core at the center, while offering practical tips, common pitfalls, and references for continuous evolution.
